I have become used to specified time limit

ServiceNow CIS-SM simulators come with the feature of limited time and the hanging clock on my head made me perform in a pressurized time frame. Earlier, i was not able to perform well but gradually i learnt the tricks of the trade and i got to know how to answer the questions based on the  ServiceNow CIS-SM certification exam. I reveal the secret how i attempted the questions. First, i performed the ones that i knew and then gradually i moved on to the ones that i found tough and it helped me complete the question set within the time frame. This is how i went along.
